JACQUARD MECHANISM FOR EMBROIDERING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 610,248, dated September 6, 1898. Application filed March 31,1898. Serial No. 675,967. (Ndmodeh) T0 at whom it may concern:

Be it known that 1, ROBERT SCOTT, lacedraftsman, a subject of the Queen of Great Britain, residing at 37 Birrell road, Sherwood Rise, Nottingham, England, have invented certain new and useful Jacquard Mechanism for Embroidery-Frames, of which the following is a specification.

The object of this invention is to apply- 3 is a horizontal section on the lines 3 3, Figs.

1 and 2. Fig. 4 is a vertical section on the line 4 4, Figs. '1 and 3. In the figures the greater part of the framing is omitted for the sake of simplicity.

a, is the embroidery-frame, which has fixed to it rails 0. free to run on grooved pulleys I), carried by levers b, pivoted at 29 The other ends of the levers Z) are pivoted to a counterbalance-weight c.

c is a rod fixed to the weight 0 and carryin g grooved rollers cirunning on the diagonal bar d of the frame 11, which is free to be moved horizontally to and fro in fixed bearings d by the bar A, to which motion is given, as hereinafter described. a

If the bar A and frame d are pushed to th right, the weightc is raised and the frame a is lowered, whereas if the bar A is pulled to the left the frame a is raised.

The to-and-fro horizontal movement is given to the frame a by the bar B, whose end carries a rack gearing with the toothed wheel e, fixed to the shaft 6, on which is a feather e f is a pinion gearing with a rack a fixed Z is a grid which reciprocates up and down through the same distance every. stitch. 1 Z is a frame connected by the rod Z to the lever 70. I

Z are verticalneedles pivoted to the top bar of the frame Z and pulled to one side or left in the path of the grid by the jacquard-needles in the ordinary way. As the grid Z rises the frame Z remains stationary unless and until the grid comes against one or other of the needles Z which has not been pulled aside by the jacquard, and the frame Z is then lifted by the grid during the remainder of the stroke of the latter, so raising the lever k and link j more or less, according to which of the needles Z3 is engaging with the grid. The link j is oscillated about its pivot j by the rod 11?, causing the rod 0 to move to and fro, the extent of its reciprocations depending on the height to which the pivot j has been raised. The jacquardcards are so punched that only one at the most of the levers It of each pair is raised at any time, as shown at Fig. 4.

The bars 0 have teeth or racks O at one side of their ends, and the bars A and B have similar teeth or racks A B on both sides. Normally the teeth on the bars 0 do not engage with those on the 'barsA and B, but when one of the leverslt is raised Joy the jacquard, asabove described, the recessk? in the plate is lifted above the ball 0 (carried by the bar 0,) so that the side of the plate 7.2 is now in contact with the ball, as shown at Fig. 4. g are projections on the side of the cam-disks g g g 9 and as the cams revolve these pro-' jections acting on any of the plates 70 which are raised press them sidewise against the bars 0, putting the teeth of the latterinto gear with the teeth on the bar A or B, as the case may be, causing this bar to move with the bar 0, and thus giving the required vertical or horizontal movements to the embroideryframe.

What I claim is- 1. The combination of a frame, two parallel bars free to movelongitudinally, mechanism actuated by the bars moving the frame in two directions at right angles to each other, second and third pairs of parallel bars, means whereby one or other bar of each of the latter pairs moves one of the first bars and pattern mechanism reciprocatin g the second and third pairs of bars.

2. The combination of a frame, a diagonal guide, a part moving in the guide and connected to the frame, two parallel bars free to move longitudinally,connections between one bar and the frame and the other bar and the guide, pattern mechanism and means actuated by it for moving the bars.

3. The combination of a frame, two parallel bars free to move longitudinally, a diagonal guide, a part moving in the guide, connections between one bar and the frame and the other bar and the guide, second and third pairs of parallel bars, means whereby one or other bar of each of the latter pairs moves one of the first bars, and pattern mechanism reciprocating the second and third pairs of bars.

4. The combination of a frame, two parallel bars free to move longitudinally, mechanism actuated by the bars moving the frame in two directions at right angles to each other, second and third pairs of parallel bars, means whereby one or other bar of each of the latter pairs moves one of the first bars, jaws on the bars of the second and third pairs,-links passing between the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a constant distance, levers pivoted to the other ends of the links, and pattern mechanism for raising the levers.

5. The combination of a frame, two parallel bars free to move longitudinally, a diagonal guide, a part moving in the guide, connections between one bar and the frame and the other bar and the guide, second and third pairs of parallel bars, means whereby one or other bar of each of the latter pairs moves one of the first bars, jaws on the bars of the second and third pairs, links passing between the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a constant distance, levers pivoted to the other ends of the links, and pattern mechanism for raising the levers.

6. The combination of a frame, two parallel bars free to move longitudinally, mechanism actuated by the bars, moving the frame in two directions at right angles to each other, second and third pairs of parallel bars, teeth on two sides of the bars of the first pair, teeth on one side of the other bars, means whereby the latter teeth are caused to engage with the former, and pattern mechanism reciprocating the second and third pairs of bars.

7. The combination of a frame, two parallel bars free to move longitudinally, a diagonal guide, a part moving in the guide, connections between one bar and the frame and the other bar and the guide, second and third pairs of parallel bars, teeth on two sides of the bars of the first pair, teeth on one side of the other bars, means whereby the latter teeth are caused to engage with the former, and pattern mechanism reciprocating the second and third pairs of bars.

8. The combination of a frame, two parallel bars free to move longitudinally, mechanism actuated by the bars moving the frame in two directions at right angles to each other,

second and third pairs of parallel bars, teeth on two sides of the bars of the first pair, teeth on one side of the other bars, means whereby the latter teeth are caused to engage with the former, jaws on the second and third pairs of bars, links passing between the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a .constant distance, levers pivoted to the other ends of the links, and pattern mechanism for raising the levers.

9. The combination of a frame, two parallel bars free to move longitudinally, a diagonal guide, a part moving in the guide, connections between one bar and the frame and the other bar and the guide, second and third pairs of parallel bars, teeth on two sides of the bars of the first pair, teeth on one side of the other bars, means whereby the latter teeth are caused to engage with the former, jaws on the second and third pairs of bars, links passing between the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a constant distance, levers pivoted to the other endsof the links, and pattern mechanism for raising the levers.

10. The combination of a frame, two paral: lel bars free to move longitudinally, mechanism actuated by the bars moving the frame in two directions at right angles to each other, second and third pairs of parallel bars, jaws on the bars of the second and third pair, links passing between the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a constant distance, levers pivoted to the other ends of the links, pattern mechanism for raising the levers, plates on the levers, teeth on two sides of the bars of the first pair, teeth on one side of the other bars, and cams acting on the plates when raised, causing them to move the bars of the second and third pairs, so making their teeth engage with those of the first bars.

11. The combination of a frame, two parallel bars free to move longitudinally, a diagonal guide, a part moving in the guide, connections between one bar and the frame and the other bar and the guide, second and third pairs of parallel bars, jaws on the bars of the second and third pairs, links passing be tween the jaws, rods pivoted to one end of the links, means for reciprocating the rods through a constant distance, levers pivoted to the other ends of the links, pattern mechanism for raising the levers, plates on the levers, teeth on two sides of the bars of the first pair, teeth on one side of the other bars,

and cams acting on the plates when raised, causing them to move the bars of the second to and third pairs, so making their teeth engage With'those of the first bars.
